A, Fundus photograph shows a dark, large, circumscribed, view-obstructing mass.
B, Transocular sonography reveals a well-marginated endophytic mass with low internal reflectivity (arrows). Subretinal effusion is also observed (arrowhead).
C, The mass located at the ciliochoroidal region is large, protuberant, and isointense to brain on a precontrast T1-weighted axial image (open arrow). Small amount of subretinal hemorrhage is noted (arrowhead).
D, T2-weighted fast spin-echo axial image also shows an intraocular mass isointense to brain.
